Question

Как изменить площадь прямоугольника если одну его сторону увеличить в 3 раза а другую уменьшить в 6 разЗАРАНИЕ СПАСИБО! =)

Answer 1

Было  х одна сторона
у другая сторона
S=x*y
стало  3х и у/6
S=3х* у/6 = ху /2

Площадь уменьшилась в 2 раза

Answer 2

Changing the Area of a Rectangle by Modifying Its Sides

To change the area of a rectangle when one side is increased by 3 times and the other is decreased by 6 times, you can follow these steps:

1. Understand the Formula for the Area of a Rectangle: - The area (A) of a rectangle is calculated using the formula: A = length * width.

2. Initial Area of the Rectangle: - Let's assume the initial length of the rectangle is L and the initial width is W. Therefore, the initial area (A_initial) is A_initial = L * W.

3. Changing the Sides: - When one side is increased by 3 times and the other is decreased by 6 times, the new length and width can be expressed as: - New length (L_new) = 3L - New width (W_new) = W/6

4. Calculating the New Area: - Using the new length and width, the new area (A_new) can be calculated as: - A_new = L_new * W_new - Substitute the values of L_new and W_new to find the new area.

5. Comparison of Initial and New Areas: - Compare the initial area (A_initial) with the new area (A_new) to observe the change in the area due to the modifications in the sides.

By following these steps, you can determine how the area of the rectangle changes when one side is increased by 3 times and the other is decreased by 6 times.
